Small-holder farmers often develop adaptable agroforestry management techniques to improve and diversify crop production. In the cocoa growing region of Ghana, local knowledge on such farm management holds a noteworthy role in the overall farm development. The documentation and analysis of such knowledge use in cocoa agroforests may afford an applicable framework to determine mechanisms driving...

13 worldwide have recommended stopping the use of antibiotic growth promoters (AGPs) and limiting the use of therapeutic antibiotics. Alternative methods are needed to control diseases and at the same time reduce the dependence on antibiotics, including improved biosecurity and disease management on farm level, vaccination programs and sustainable prophylactics intervention such as probiotics, ...

Fruit and soil yeasts isolated from the Amazon, Atlantic Rainforests and an organic farm were screened for killer activity against yeasts. Killer yeasts were then tested against the phytopathogen Moniliophthora perniciosa (syn. Crinipellis perniciosa) and a Dipodascus capitatus strain and a Candida sp strain inhibited its growth.

3 Fish farms represent a growing source of disturbance to shallow benthic ecosystems like 4 seagrass meadows. Despite some existing insights on the mechanisms underlying decline, efficient tools 5 to quantitatively predict the response of benthic communities to fish farm effluents have not yet been 6 developed. We explored relationships of fish farm organic and nutrient input rates to the sedim...

This paper examines the factors that influence the earned income of organic farmers, given their decisions to engage in local selling. The model explicitly accounts for the sorting of producers across different levels of commitment to local sales on the basis of both observable and unobservable heterogeneity. The significant selectivity coefficients confirm that when producers choose to market ...

Orius insidiosus (Say) and O. pumilio (Champion) were confirmed to be sympatric in north central Florida as the major predators of the Florida flower thrips, Frankliniella bispinosa (Morgan), on flowers of Queen Anne's lace, Daucus carota L. and false Queen Anne's lace, Ammi majus L. F. bispinosa was the predominant thrips observed on both flowers but colonized D. carota to a greater extent an...

The purpose of this study was to assess the association of bulk tank milk standard plate counts, bulk tank coliform counts (CC), and the presence of Staphylococcus aureus in bulk tank milk with various management and farm characteristics on organic and conventional dairy farms throughout New York, Wisconsin, and Oregon. Data from size-matched organic farms (n=192), conventional nongrazing farms...

The concept of socio-ecological resilience is applied to agricultural systems in general and to the farm level in particular. Resilience has three defining characteristics: the amount of change the system can undergo while maintaining its functions and structures, the degree of self-organization, and the capacity for learning and adaptation. To assess the resilience of a farming system, various...
